  third 
  as 
  wide 
  as 
  the 
  segment 
  behind 
  it; 
  it 
  is 
  thick, 
  and 
  about 
  as

  The

  the 
  maxillary 
  palpi 
  

   are 
  short, 
  projecting 
  but 
  slightly 
  beyond 
  the 
  ends 
  of 
  the 
  labial 
  palpi 
  ; 
  

   they 
  are 
  three-jointed 
  ; 
  the 
  first 
  but 
  slightly 
  shorter 
  than 
  the

  third 
  

   but 
  half 
  as

  Labial 
  palpi

   Three 
  pairs 
  of 
  well-developed 
  legs, 
  which 
  are 
  two-jointed, 
  ending 
  in 
  a 
  

   single 
  stout 
  claw. 
  The 
  end 
  of 
  the 
  body 
  is 
  suddenly 
  somewhat 
  flattened 
  

   and 
  bent 
  over 
  onto 
  the 
  ventral 
  side, 
  and 
  is 
  armed 
  above 
  with 
  two 
  paral- 
  

   lel, 
  flat, 
  blade-like 
  chitinous 
  appendages, 
  a 
  little 
  curved 
  and 
  appressed 
  

   to, 
  though 
  free 
  from, 
  the 
  surface 
  on 
  which 
  they 
  rest, 
  reaching 
  to 
  the 
  tip 
  of 
  

   the 
  body, 
  and 
  curved 
  slightly 
  backward. 
  The 
  segments 
  of 
  the 
  body 
  

   are 
  quite 
  convex, 
  the 
  sutures 
  deeply 
  impressed, 
  and 
  the 
  exposed 
  parts 
  of 
  

   the 
  body 
  are 
  covered 
  with 
  fine 
  hairs. 
  The 
  prothoracic 
  segment

   slightly 
  reddish, 
  pale

  is 
  noticed 
  here

  The 
  Californian 
  Lapper 
  Moth, 
  Gastropacha 
  calif 
  ornica 
  Pack. 
  

  

  This 
  and 
  the 
  following 
  moth 
  are 
  somewhat 
  annoying 
  insects 
  in 
  Cali- 
  

   fornia, 
  feeding 
  upon 
  the 
  oak, 
  and 
  at 
  my 
  request 
  Mr. 
  Henry 
  Edwards 
  

   has 
  furnished 
  me 
  with 
  the 
  following 
  account 
  of 
  them 
  : 
  

  

  "The 
  moth 
  lays 
  its 
  eggs 
  in 
  June, 
  and 
  they 
  must 
  remain 
  unhatched 
  

   until 
  the 
  following 
  spring. 
  Just 
  when 
  the 
  young 
  shoots 
  of 
  the 
  oaks 
  

   {Quercus 
  agrifoUa 
  Nee) 
  begin 
  to 
  appear, 
  the 
  larvae 
  make 
  their 
  appear- 
  

   ance. 
  also, 
  spinning 
  thin 
  and 
  irregular 
  webs 
  over 
  the 
  branches 
  of 
  the 
  

   trees. 
  In 
  these 
  webs 
  they 
  house 
  mostly 
  during 
  the 
  heat 
  of 
  the 
  day, 
  

   but 
  sally 
  forth 
  in 
  the 
  evening 
  and 
  at 
  night 
  for 
  food. 
  In 
  this 
  way 
  they 
  

   will 
  soon 
  strip 
  a 
  tree 
  of 
  its 
  leaves, 
  though 
  it 
  is 
  well 
  to 
  say 
  that 
  the 
  oaks 
  

   do 
  not 
  seem 
  to 
  be 
  permanently 
  aft'ected, 
  as 
  they 
  soon 
  send 
  forth 
  fresh 
  

   shoots, 
  and 
  toward 
  the 
  time 
  that 
  the 
  caterpillars 
  undergo 
  their 
  change 
  

   to 
  the 
  chrysalis 
  they 
  are 
  green 
  and 
  gay 
  again. 
  The 
  larvae 
  retain 
  the 
  

   shelter 
  of 
  their 
  web 
  until 
  after 
  the 
  third 
  month, 
  when 
  they 
  wander 
  

   away 
  singly, 
  are 
  found 
  everywhere, 
  becoming 
  sometimes 
  a 
  complete 
  

   nuisance 
  in 
  gardens 
  and 
  fields. 
  They 
  feed 
  in 
  their 
  more 
  mature 
  stages 
  

   upon 
  many 
  plants 
  besides 
  the 
  oak, 
  eating 
  with 
  avidity 
  willows, 
  ash, 
  

   JEscuIus 
  californica, 
  Photinia 
  arhutifoUa, 
  Arbutus 
  menziesii^ 
  as 
  well 
  as 
  

   apple 
  and 
  pear 
  trees. 
  Toward 
  the 
  end 
  of 
  May 
  they 
  spin 
  their 
  cocoons, 
  

   seeming 
  to 
  have 
  no 
  choice 
  of 
  locality, 
  but 
  fixing 
  themselves 
  wherever 
  

   they 
  may 
  chance 
  to 
  be, 
  either 
  on 
  walls, 
  palings, 
  trunks 
  or 
  branches 
  of 
  

   trees, 
  stems 
  of 
  grapes, 
  or 
  among 
  the 
  leaves 
  of 
  herbaceous 
  plants. 
  The 
  

   time 
  in 
  the 
  chrysalis 
  state 
  is 
  about 
  eighteen 
  to 
  twenty-one 
  days, 
  so 
  that
